The 2026 FIFA World Cup generated more than $20 billion in onchain prediction-market volume during the tournament, according to blockchain analytics firm Chainalysis, making football’s biggest international competition the dominant driver of activity across the sector during the month-long event.
Chainalysis estimated that World Cup-related contracts represented about 63% of all onchain prediction-market volume over the tournament period. The figure points to a market increasingly shaped by short-term contracts on live events, where users trade positions on match results, individual performances and highly specific moments around major sporting contests.
The report did not identify every platform included in its World Cup estimate, limiting direct comparisons with data that track a narrower group of venues. Even so, the scale of activity places the tournament among the largest concentrated events yet recorded in onchain prediction markets.
Ronaldo market drew nearly $50 million
One of the largest single World Cup contracts focused on whether Cristiano Ronaldo would cry following what was widely expected to be his final appearance at the tournament. The market generated nearly $50 million in volume, Chainalysis reported, and contracts backing the “yes” outcome paid out.
The wager illustrates how prediction markets have moved beyond conventional scorelines and tournament winners. Users increasingly trade contracts tied to emotional reactions, player statistics and other event-specific outcomes that can attract attention independently of the matches themselves.
Such markets can draw substantial turnover because shares often change hands repeatedly before an outcome is settled. Reported volume measures the total value traded, rather than the amount ultimately paid to winners or the size of a platform’s revenue.
World Cup activity also surged around major knockout fixtures, according to Chainalysis. Daily wagers reached hundreds of millions of dollars as users traded contracts linked to team advancement, match winners, player props and the eventual champion.
Sports dominated leading venues during the tournament
Separate market data covering the broader sports calendar recorded roughly $54 billion in sports prediction-market volume between June 11 and July 19, a period that overlapped with the World Cup, the NBA Finals, Major League Baseball’s regular season and Wimbledon.
That broader total cannot be treated as a direct measure of World Cup betting. Chainalysis’ $20 billion estimate covers World Cup markets but does not specify the complete platform set, while the $54 billion sports figure covers multiple events and a different dataset. The two figures nonetheless show how heavily sporting events concentrated prediction-market trading during the summer.
Sports contracts accounted for roughly 70% to 85% of volume on the two largest venues tracked in the category-level data during the World Cup, Chainalysis said. Their share fell after the final, dropping to about 60% on one venue and 50% on the other.
The post-tournament decline suggests the World Cup supplied a temporary but unusually powerful source of liquidity. Large global events create a steady sequence of fixtures, news cycles and settlement points, encouraging users to enter and exit positions throughout the day rather than making a single wager before an event begins.
That pattern can improve trading conditions in actively followed contracts by bringing more buyers and sellers into the market. It does not remove the risks associated with thinly traded markets outside headline events, unclear contract wording, sudden price moves or disputes over how outcomes are resolved.
Illicit-activity flags remained limited
Chainalysis also examined risk signals among wallets that participated in World Cup markets. Fewer than 1% of approximately 400,000 wallets interacting with those markets had a history of illicit activity, according to the firm.
The largest identified category of suspicious funds was connected to a sanctioned venue, totaling about $5.4 million. Wallets associated with scams, stolen funds and over-the-counter brokers accounted for smaller portions of the activity identified by Chainalysis.
The findings offer a narrower view than a full assessment of platform compliance or user behavior. Blockchain analytics can trace known or suspected addresses and their transaction histories, but it cannot establish the identity or intent of every participant using a wallet. The data does show that flagged funds represented a small share of the World Cup-related wallet activity observed by the firm.
Regulatory pressure remains a constraint
The growth in sports event contracts continues to collide with regulatory concerns in the United States, where state officials have challenged some products as unlicensed sports betting rather than federally regulated event contracts.
That dispute carries practical consequences for platforms seeking to turn tournament-driven volume into a permanent business. Sports markets can bring frequent trading and mainstream attention, but they also face closer scrutiny than contracts on economic data, elections or other public events.
The World Cup’s $20 billion onchain estimate therefore captures both the opportunity and the constraint facing prediction markets. A globally followed tournament gave the sector an enormous pool of active users and contracts with clear settlement dates. Whether platforms can retain that activity after the football calendar subsides will depend less on viral one-off markets and more on liquidity, reliable resolution processes and the legal treatment of sports-based contracts.
